need immediate assistance to get that answer how ????????

please step by step show me ..........

Extracted text: Fig. 4 Fig. 5 Detail 30° Air flow A 950 125 B. 100mm 60mm - 3000- 800 300 Dimensions in millimeters 5. The car shown in Fig. 5 complete with driver has a mass of 815 kg and without the two aerofoils has a 50% - 50% front - rear weight distribution at a certain speed at which there is no lift on the car. It is estimated that at this speed each of the aerofoils A, and A, will generate 2 kN of downforce L and 250 N of drag force D on the car. Determine the vertical reactions under the two pairs of wheels at that speed when the aerofoils are added. Assume that the addition of the aerofoils does not affect the drag and zero-lift conditions of the car body itself and that the engine has sufficient power for equilibrium at that speed. The weight of the aerofoils may be neglected. [ Ans : A- 5754 N,B- 6241 N ]
